Every software system has an architecture, whether it was developed deliberately or arose by chance. Whether small services, cloud solutions, systems of systems, digital ecosystems, or platforms - the same applies to all of them: only those who know the software architecture of their systems and master the complexity of their software systems through architecture can achieve their business goals and desired quality characteristics - reliably, effectively, and efficiently. It is important to note that architecture is not an end in itself or merely a piece of necessary documentation. On the contrary, software architecture is an investment in planning, design, forecasting, communication, and control that pays off when business and technical decisions are made on a sound basis and the solution is built correctly and with an eye to the future.
